User Interface / Touch Control Communication Error
Symptom
Condensation or water droplets form on the control panel or drip from the door after cooking.
Excessive Condensation / Steam Management Issue
Symptom
Food is unevenly cooked; back of the oven is hotter than the front or one side browns more.
Uneven Heat Distribution
Symptom
Oven clock and timer reset every time power is switched off briefly or there is a minor power dip.
Loss of Backup Power / RTC Retention
Symptom
Oven display and controls are completely dead; oven does not respond at all.
No Power / Dead Appliance
Symptom
Oven display works but buttons or touch controls do not respond or respond intermittently.
Unresponsive Control Panel
Symptom
Oven does not heat at all; display and lights work but no warmth in any mode.
Total Heating Failure
Symptom
Oven door will not close fully; there is a gap and heat escapes during operation.
Door Misalignment / Hinge Wear
Symptom
Oven door will not open after cooking; no error code is shown.
Door Latch Stuck / Residual Locking
Symptom
Oven emits a burning smell or smoke during normal cooking (not during first use or pyrolytic cleaning).
Overheating of Spills / Insulation or Wiring
Symptom
Oven emits a persistent chemical or plastic smell even after several uses.
Off-Gassing from New Components or Contamination
Symptom
Oven fan continues to run for an unusually long time after cooking has finished.
Cooling Fan Overrun / Temperature Sensing
Symptom
Oven fan runs but there is no heat in convection or fan-assisted modes.
Convection Mode Heating Failure
Symptom
Oven glass door becomes excessively hot to the touch during normal baking (risk of burns).
Door Cooling / Insulation Fault
Symptom
Oven heats but does not reach the set temperature; food takes much longer than expected to cook.
Underheating / Temperature Calibration Error
Symptom
Oven interior enamel is cracked or flaking; rust spots may appear.
Cavity Enamel Degradation
Symptom
Oven interior light does not work, but heating and other functions are normal.
Cavity Lamp Failure
Symptom
